The compressor can be used to inflate car and bicycle tires. It will also handle inflating inflatable items, such as boats, air mattresses, and balls. All that is needed is to select the appropriate adapter for the task. Three adapters (as well as a needle for balls, a bicycle adapter, a car hose, and documentation) are included in the package. The battery and charger are not included in the compressor package. The model belongs to the Finepower OneBase20 platform. This means that a battery compatible with any device on this platform can be used. The battery and charger are not included in the package of this power tool. An important design feature of the FinePower OneBase CAP7 compressor is the display, which shows the pressure. Control buttons are located beneath the display. The ergonomic shape of the handle contributes to ease of use. It is also worth noting the compactness of the compressor.
